How good to keep SRVCC “Off” and CSFB “On” or vice-versa in VoLTE enabled network?
Hello All.
How good to keep SRVCC “Off” and CSFB “On” or vice-versa in VoLTE enabled network?
The best setting for you depends on your specific needs and the coverage in your area. Here’s a breakdown of the advantages and disadvantages of each setting:
Better call quality: VoLTE calls generally offer superior sound quality compared to CSFB calls. By keeping SRVCC off, you prioritize remaining on VoLTE for as long as possible.
Faster call setup: VoLTE calls connect faster than CSFB calls.
Lower battery consumption: VoLTE is more efficient than CSFB, so keeping it active can save battery life.
Dropped calls: If you leave an area with VoLTE coverage without CSFB enabled, your call will drop instead of seamlessly shifting to 2G/3G networks.
Limited coverage: You might be able to make data calls in non-VoLTE areas even with SRVCC off, but voice calls will only work if you have 2G/3G coverage.
Seamless call handovers: With SRVCC, your call will automatically switch to 2G/3G networks without interruption if you move out of a VoLTE area.
Wider coverage: You can make and receive calls even in areas without VoLTE coverage as long as there’s 2G/3G signal.
Potential call quality drop: Switching from VoLTE to 2G/3G might affect call quality, especially in areas with weak signal strength.
Slightly slower call setup: SRVCC handovers add a small delay to call setup compared to direct VoLTE calls.
Higher battery consumption: The network switch during SRVCC handovers can temporarily increase battery usage.
Ultimately, the best setting is the one that works best for your needs and preferences.
